Question

【題目】根據(jù)短文理解，選擇正確答案。
Some educators told us that more years of school could help students get higher scores on intelligence tests. That was a finding of a study of teenage males in some countries. Now, another research shows that physical activity may help students do better in their classes.
The research comes as educators in some countries are reducing time for activities like physical education. They are using the time instead for academic（學(xué)術(shù)的）subjects like math and reading. The studies appeared between 2008 and 2014. They included more than 55, 000 children, aged 6 to 18.
Amika Singh:“ According to the results of our study, we can conclude that being physically active is beneficial for academic performance. There are, first, Physiological explanations, like more blood flow, and so more oxygen to the brain. Being physically active means there are more hormones(荷爾蒙)produced like endorphins(內(nèi)啡肽). And endorphins make your stress level lower and your mood improved, which means you also perform better.”
Also, students taking part in organized sports learn rules and how to follow them. This could improve their classroom behavior and help them keep their mind on their work.
The study leaves some questions unanswered, however. Ms. Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement. This is because of differences among the studies.
The researchers said they found only two high-quality studies. They needed more high-quality studies to confirm (證實(shí)) their findings. They also pointed out that “results for other parts of the world may be quite different.”
Still，the general finding was that physically active kids are more likely to do better in school. Ms. Singh says schools should consider that finding before they cut physical education programs. Her paper on “Physical Activity and Performance at School” is published in the Archives of Pediatric and Adolescent Medicine.

（3）The underlined sentence in Paragraph 6 probably means ________.
A.good marks result from high-quality study.
B.findings are probably different in different areas.
C.physical activity will spread all over the world.
D.academic performance depends on the surroundings.

Answer 1

【答案】
（1）B
（2）D
（3）B
（4）A
【解析】本文介紹了一項(xiàng)新的研究發(fā)現(xiàn)：體育活動(dòng)對(duì)學(xué)生有益。而現(xiàn)在有教育者要減少體育教育的時(shí)間，作者呼吁我們要重視體育教育。

⑴主旨大意。根據(jù)文章第一段最后一句Now, another research shows that physical activity may help students do better in their classes.可知另外一項(xiàng)研究顯示體育活動(dòng)可以幫助學(xué)生在課堂里表現(xiàn)得更好，能夠取得更好的成績(jī)。文章對(duì)這一研究發(fā)現(xiàn)展開詳細(xì)說明。故B項(xiàng)正確。

⑵推理判斷。根據(jù)第二段前兩句The research comes as educators in some countries are reducing time for activities like physical education. They are using the time instead for academic（學(xué)術(shù)的）subjects like math and reading.正是因?yàn)橐恍┙逃�者正在減少體育教育的時(shí)間，而把更多的時(shí)間用在了專業(yè)性更強(qiáng)的數(shù)學(xué)或閱讀學(xué)科方面。所以人們才進(jìn)行了這項(xiàng)研究。故D項(xiàng)正確。

⑶句意理解。根據(jù)劃線句前兩句The researchers said they found only two high-quality studies. They needed more high-quality studies to confirm (證實(shí)) their findings.可知研究人員認(rèn)為他們只進(jìn)行了兩次高質(zhì)量的研究，還需要更多的研究來證實(shí)這個(gè)理論。也許在其他地方的研究會(huì)得出不同的結(jié)果。故B項(xiàng)正確。

⑷目的意圖。根據(jù)文章最后一段Still，the general finding was that physically active kids are more likely to do better in school. Ms. Singh says schools should consider that finding before they cut physical education programs.可知參加體育活動(dòng)對(duì)學(xué)生有很大的好處，學(xué)校在減少體育課程之前要三思而后行。呼吁我們要高度重視體育教育。故A項(xiàng)正確。
